Sodium-assisted TiO2 nanotube arrays of novel electrodes for photochemical sensing platform

Influence of laser and alkali treatment on an Ag/TiO2 nanotube based dopamine sensor

“…Further, the sodium hydroxide treated T-NTs for 30 min form a very thin sodium titanate layer on the surface of the plain T-NTs without changing the morphology of the nanotubes (shown in section 3.2 (figure 4(a)). The peaks related to sodiumhydroxide encapsulated on TiO 2 nanostructures were absent in XRD analysis (in section 3.2) due to the amorphous nature of the sodium titanate layer [16]. When the soaking time was exceeded above 30 min, it leads to the excess formation of sodium titanate over the surface, which corrodes and disrupts the nanotubular structure and thus degrades their electrochemical performance [14].…”

“…It exhibits superior electronic contact and improved chemical stability for the majority of biomedical applications [14,15]. It has been shown that NaOH treatment helps in electron transport, reduces recombination of electron-hole pairs, and improved conductivity for photoelectrochemical sensing applications [16]. It has been further illustrated that Na forms a strong ionic bond with T-NTs leading to effective charge transfer and also modify the band structure of TiO 2 energy bands at more positive energy levels [17].…”

“…In order to improve the mechanical stability of the formed gel layer, it was dehydrated and densified to form a sodium titanate layer by annealing at 450 °C (figure 1) [18]. However, the results showed that the modification with sodium hydroxide was only confined to the nanotube surface and had little influence on the crystal structure of the nanotubes [16]. Therefore, to induce changes in the crystallographic structure of the alkali-modified substrate, a second treatment (laser irradiation) was done.…”

Transparent anti-fingerprint glass surfaces: comprehensive insights into theory, design, and prospects

“…It is imperative to highlight that, due to the continual advancements in anti-fingerprint technology research, anti-fingerprint coatings have been adopted across a myriad of modern applications. Such applications include control panels in automobiles, 6,7 high-gloss automotive plastics, 8,9 optical lenses, [10][11][12][13] architectural glazing, 14,15 elevator interface panels, 16 and several other domains, [17][18][19][20] as illustrated in Fig. 1.…”

Development of polyindole/tungsten carbide nanocomposite-modified electrodes for electrochemical quantification of chlorpyrifos

“…In this context, common dopants employed for PIN are gold [51], oxides of zinc and nickel [52], tin [53], iron [54], vanadium [55] and copper [56]. Nanocomposite of titanium carbide and poly(3,4-ethylenedioxythiophene) were prepared as an alternative electrocatalyst for dye-sensitized solar cell applications [57][58][59][60]. The present work proposed a novel and economical sensor for the trace level electrochemical detection of CHL, by utilizing WC-doped PIN nanocomposite.…”
